Systems and methods for alternating material brake disk stack

Abstract

Dissimilar aircraft brake systems for use in, for example, an aircraft are provided herein. In this regard, a system is provided comprising a carbon/carbon (“C/C”) rotor disk adjacent to a ceramic matrix composite (“CMC”) stator disk. In various embodiments, a system is provided comprising a CMC rotor disk adjacent to a C/C stator disk.

The invention claimed is: 
     
       1. A brake disk stack comprising a carbon/carbon (“C/C”) rotor disk adjacent to a ceramic matrix composite (“CMC”) stator disk, an end plate comprising a CMC component and a pressure plate comprising a CMC component. 
     
     
       2. The brake disk stack of  claim 1 , wherein the C/C rotor disk is of substantially the same thickness as the CMC stator disk. 
     
     
       3. The brake disk stack of  claim 1 , wherein a thickness of the C/C rotor disk is not equal to a thickness of the CMC stator disk. 
     
     
       4. The brake disk stack of  claim 3 , wherein the thickness of the C/C rotor disk is equal to from about 1.5 to about 3 times the thickness of the CMC stator disk. 
     
     
       5. The brake disk stack of  claim 1 , wherein a second C/C rotor disk is adjacent to the CMC stator disk. 
     
     
       6. The brake disk stack of  claim 1 , wherein a C/C stator disk is adjacent to the CMC rotor disk. 
     
     
       7. A method of manufacturing a brake disk stack comprising:
 disposing a carbon/carbon (“C/C”) rotor disk in the brake disk stack; 
 disposing a ceramic matrix composite (“CMC”) stator disk adjacent to the C/C rotor disk; 
 placing an end plate comprising a CMC component and a pressure plate comprising a CMC component in the brake disk stack. 
 
     
     
       8. The method of  claim 7 , wherein the C/C rotor disk is of substantially the same thickness as the CMC stator disk. 
     
     
       9. The method of  claim 7 , wherein a thickness of the C/C rotor disk is not equal to a thickness of the CMC stator disk. 
     
     
       10. The method of  claim 7 , wherein the thickness of the C/C rotor disk is equal to from about 1.5 to about 3 times the thickness of the CMC stator disk. 
     
     
       11. The method of  claim 7 , further comprising disposing a second C/C rotor disk adjacent to the CMC stator disk.
